The Sidi Vertigo has always been right at the sweet spot for sport riders not looking to break the bank too much for a pair of protective riding boots. The Sidi Vertigo 2 sticks to the same formula. Most important new feature, is the ankle brace system, diverted from the likes of the Sidi ST and Vortice boots. This means the Vertigo 2 improves on the Vertigo in terms of safety and protection. The ankle brace helps prevent injuries caused by twisting your feet in ways that should not be possible. The Tecno-3 adjustment rotor has been relocated to the side of the boot for an easier reach. This calf adjuster, together with the long zipper on the inside of the foot, ensures easy entry and perfect adjustability.In terms of impact protection, you will find a large TPU shin plate, a TPU heel protector and replaceable toe sliders.
